Subject Re: [cli] - how to use CLI for Java like properties
Date Sat, 24 Dec 2011 13:48:49 GMT
I *think* because you created them all with "D" and so it only kept the
last one. I think tobdo what you want you would call create with
"DnodeName" for example.

Why do you want this at all? Why not just let the JVM parse the properties
from the cmd line?
